Under the new law, which passed last month, all single-use cups, plates and other dishware sold in the country will need to be compostable and made at least partly of bio-sourced materials. Businesses have been given until Jan. 1, 2020 to comply with the measure.

Though environmentalists and others have rejoiced in the passage of the new measure, it has also been met with criticism. At least one packaging industry lobbyist has threatened to take legal action against France for violating European Union rules on the free movement of goods, AP reported.

France, which hosted the landmark Paris Climate Change Conference last year, has stepped up its commitment to climate action and other environmental issues. The country’s plastic dishware ban follows a similar prohibition on plastic bags, which began in July.
